T1059.001 Command and Scripting Interpreter: PowerShell
T1059.007 Command and Scripting Interpreter: JavaScript
The PDF file contains XFA (XML Forms Architecture) data, which is known to be a vector for exploits. Specifically, the 'CVE_2010_0188' heuristic indicates exploitation of a LibTIFF vulnerability within Adobe Reader. The 'CLAMAV_DETECTION: Js.Exploit.HTML-30' suggests that the exploit payload involves JavaScript. The embedded URL is likely part of the exploit chain, potentially used to download further stages. The document body contains obfuscated JavaScript, which is likely responsible for executing the exploit.

Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188PDF contains the CVE-2010-0188 exploit template: XFA JavaScript heap-spray setup, a generated TIFF image payload, and assignment of that TIFF data to an XFA image field rawValue to trigger Adobe Reader's LibTIFF parser.

ClamAV: Js.Exploit.HTML-30 critical CLAMAV_DETECTIONClamAV detected this file as malware: Js.Exploit.HTML-30
-
XFA numeric character-table eval stager high PDF_XFA_NUMERIC_EVAL_STAGERPDF XFA initialize script reads numeric form data from rawValue, maps the values through a short character table, and evals the reconstructed stage. This is an exploit-kit staging technique even when the final decoded layer remains encoded.
